I have an 802.11g home network. My laptop uses Intel ProSet/Wireless to
manage WiFi connections. Sometimes the Intel ProSet/Wireless icon in
the task bar shows poor signal quality event though the signal strength
indicator in the ProSet/Wireless main screen shows five bars (the
maximum). My laptop is located less than three fee from the wireless
router. I have tried different channels with no effect.

1) What metric does Intel ProSet/Wireless use to determine signal
quality?

2) How can I determine the cause of the intermittent poor signal
quality?

Any suggestions or pointers to reference material would be most welcome.

Sgnal interferance is normal. Can be cause by almost any
environmental causes:

-- Microwave ovens
-- Cordless phones
-- Additional wifi wireless networks in your area
-- Cell phone
-- Power

Thanks. If interferance that causes the network to fail was normal no
one would use wireless networks.<g> I know it is not my microwave oven
or cordless phones (different frequency). There are no other wifi
networks within range. There are no cell phones in use in my house when
the problem occurs. The house next to me is vacant at the moment so I
know the problem is not there.

Any suggestions for determining the cause or reducing its impact?

Did you scan for the Wireless network in your area?

Where is the router placed? It should be in the center of your
network area.

Walls, eleectronic equipement and appliances can "reflect" some of the
signals.

Yes. There are a couple of other networks but they are not close and
none is on the channel I am using.

It is not but it cannot be moved. Location cannot be relevant to the
problem.

The problem is that the signal quality as reported by Intel
ProSet/Wireless suddenly drops dramatically for a period of time that
may range from minutes to hours then suddenly returns to its normal
value. Walls cannot cause that effect.

I am beginning to suspect that it must be some kind of interference and
that once I eliminate possible causes in my home there is nothing else
I can do. Is that the case?
